Web1 okt. 2024 · Nowadays, you’d be hard-pressed to find ocean waters less than 100 meters deep that don’t contain calcifying plankton. Despite their teeny size, they may account for nearly 12% of the total biomass in the oceans. And they’ve completely altered the way carbon moves around the planet. Web4 jul. 2008 · If emissions can be reduced after the year 2050 and capped at 1500 Pg C, surface ocean pH would decline by ∼0.35 units relative to preindustrial levels. The aragonite saturation state in the warm surface ocean would drop from ∼3.5 to ∼2.1 under this scenario (see supporting online material).
